Description

 CONNECTOR WITH SEALING ELEMENT AND ADAPTED CONNECTOR PARTS

The present invention relates to a connector comprising at least a first connector part and at least one second connector part, the connector parts being connectable to one another in a fluid-tight manner and being lockable to one another via at least one closure element, one of the connector parts having at least one sealing element which opens the flow-through barrier in the closed state and is preferably sealed , in particular a septum or a sealing disk, and the other of the connector parts has at least one opening element for opening the sealing element and wherein one of the connector parts has at least one projection and the other of the connector parts at least one receptacle.

In extracorporeal blood treatment, treatment liquids are usually provided in bags. Depending on the type of therapy and patient needs, a variety of different treatment fluids are provided, which may differ in composition and concentration of the individual solution components. The bags generally have a connector part which can be connected to a complementary connector part, ie to a connector part with which the bag connector part can be connected, in order to remove the treatment liquid for treatment from the bag and, for example, to transfer it into a tube system on which the complementary connector part is arranged.

In particular, in the event that multiple treatment fluids are used simultaneously in the therapy, there is a risk that individual bags are not linked by confusion with the designated ports of a hose system. This may result in the wrong fluid being used for blood treatment or other treatment, and in the worst case infused into a patient, which may involve significant health risks.

Therefore, there is a need to provide a connector that allows a bag to be assigned a type of treatment liquid even to just one designated port, so that confusion is excluded. From the prior art according to WO 09/024807 A1 it is known to provide a connector of two connector parts, in which on one connector part locking projections and on the other connector part complementary projections are arranged, which cooperate in the connected state and in this way a Konnektierungssignal Furthermore, it is known from WO11 / 131783 A2 to connect a medicament container to an injection device via a connector, which discloses encoding the connection of complementary connector parts.

The present invention has the object of developing a connector of the type mentioned in such a way that it can be particularly reliably prevented that a patient due to an oversight incorrect treatment liquid is supplied. This object is achieved by a connector having the features of claim 1. Thereafter, it is provided that the opening element and the flow blocking and openable, ie revealable sealing element, in particular the septum, a sealing disc or the like are arranged to each other such that the opening element, the sealing element, in particular the septum, etc. opens only if the projection is inserted in the receptacle.

Preferably, the two connector parts are connector parts which can be connected to one another in the manner of a bayonet closure.

Preferably, the receptacle and the projection are circumferentially on the connector parts.

Moreover, it is conceivable that a connector part has an opening element, such as a cone, which in a certain position of the connector parts interacts with a septum or the like, for example with a slotted seal, such that the opening element opens the septum. However, this is only possible if the projection is received in the receptacle, which in turn is only the case when the two connector parts match, i. E. are complementary and what is not the case if the connector parts do not match. In this way, opening of the septum is prevented in the case of non-mutually complementary connector parts, since in this case the projections can not or at least not be inserted into the receptacle such that the opening element opens the septum.

This means that the septum or the like remains closed in this case and the administration of a wrong fluid to the patient is excluded. The projection and the recording, which serve as coding elements thus not only have the task, the two connector parts z. B. form-fitting to each other or serve not only as coding, but also provide a solution to the security need, according to which in a Fehlkonnektion, ie at a Konnek- tion of non-complementary connector parts, the administration of a wrong treatment liquid is reliably avoided.

According to the invention, it is thus provided that the opening element of one connector part can only break through or penetrate the septum or the like, preferably the slot septum of the other connector part, if the projection and the receptacle on the connector parts are complementary, i. if the connector parts match each other. If this is not the case, the opening element can not break or open the septum, so that a faulty infusion or administration of a treatment liquid is reliably prevented.

The opening element may preferably be a fluid channel of one of the connector parts.

The present invention furthermore relates to a connector comprising at least one first connector part and at least one second connector part, wherein the connector parts can be connected to one another in a fluid-tight manner and locked to one another via at least one closure element, one of the connector parts having at least one sealing element with an opening, in particular a sealing ring, and the another of the connector parts has at least one contact surface for the sealing element, and wherein one of the connector parts has at least one projection and the other of the connector parts at least one receptacle, wherein the sealing element and the abutment surface are arranged to each other, that a fluid-tight connection between the first and the second connector part only exists when the projection is inserted into the receptacle. If the connection of the two connector parts is not carried out correctly, a leak indicates this because there is no fluid-tight connection between the two connector parts in this state. A fluid-tight connection in which leakage does not occur outwardly exists in this embodiment of the invention only when the connection is made correctly, ie when said projection is inserted into the receptacle.

Instead of the sealing ring, any other suitable sealing element may be used, so that the term "sealing ring" is not only an annular seal, but representative of circumferential sealing elements (e.g., sealing sleeve, perforated disc, square rings, etc.) with an opening for receiving a terminal support.

The present invention furthermore relates to a connector comprising at least one first connector part and at least one second connector part, the connector parts being connectable to one another in a fluid-tight manner and being lockable to one another via at least one closure element, one of the connector parts having at least one projection and the other of the connector parts having at least one receptacle wherein the projection is insertable into the receptacle with complementary connector parts.

In this case, it is provided according to the invention that the projection or the receptacle is arranged on an additional part, preferably on an annular or sleeve-shaped additional part, which is guided over a section of the connector part and preferably over its base body. In this case, the projection and / or the receptacle is arranged on a separate part which is inserted over the base body. This structure is particularly advantageous from an economic point of view, since only a single basic body type has to be produced, which can be combined with a multiplicity of coding means and closure means.

A combination of two or all of the three inventive ideas according to claims 1 to 3 is conceivable and encompassed by the invention. So is It is conceivable that the connector according to claim 3 according to the features of claims 1 or 2 or according to the features of claim 1 and additionally according to the features of claim 2 is formed. It is also conceivable that the connector according to the features of claim 1 is additionally designed according to the features of claim 2.

In a further embodiment of the invention it is provided that the closure element is formed by at least one pin and by at least one groove-shaped receptacle for this pin, wherein it is preferably provided that the groove is formed such that it extends over a portion in an axial direction of the connector part and extends over a partial area in the circumferential direction of the connector part, so that a locking and a rotational movement of the two connector parts relative to each other is required for locking. In this case, the connection of the two connector parts is thus comparable to a bayonet closure.

On the groove, one or more locking elements may be provided, which are contacted by the pin upon reaching the locking position of both contact parts. These locking elements can serve as a backup of the lock and also cause when sweeping the pin noise, so that the user is acoustically perceived that the locking position is reached. Alternatively or additionally, haptic feedback upon reaching the locked position, i. when the pin snaps over the locking element, conceivable and covered by the invention with.

It is preferably provided that the pin is visible upon reaching the locking position, so that a visual control of the locking position is possible.

In a further embodiment of the invention, it is provided that the additional part or another color marking, which is located on the first connector part, is color matched to the second connector part. The same can also be said for the second connector part apply. Thus, it is possible via a color design of the two connector parts or additional elements, such as rings, etc., to indicate that the two connector parts are complementary, that can be connected to each other.

It is preferably provided that the additional part or the other marking element are arranged such that they are visible even in the connected state of the connector parts, so that an optical control of the complementary connector parts is possible.

In a further embodiment of the invention it is provided that the additional part has a pressing surface for the sealing element, such as the ring seal or septum and that the connector part on which the additional part is arranged, has a sealing surface on which the sealing means, such as Ring seal or the septum is applied. In this case, the additional part fulfills not only the function to carry the projection or the receptacle, but in addition also the fixation of the sealant, in particular the ring seal or the septum on the connector part.

The term "sealing element" used below is to be understood as meaning not only sealing rings in the manner of a septum, but also representative of any sealing elements which can be opened in a sealing manner or already have an opening for receiving a sealing surface of a connecting piece.

In a further embodiment of the invention it is provided that the first or the second connector part has a base body to which the additional part is applied, wherein the base body has one or more latching lugs, which engage in at least one opening in the additional part, wherein the connection between Latches and breakthrough is preferably designed such that it is not manually releasable. Thus, it is conceivable, for example, aufzustecken on a base body or on a portion of the body, the additional part and z. B. to lock by latching, preferably vorgese- hen is that the additional part after the production of the locking connection can not be solved or only with considerable effort from the body.

Furthermore, it can be provided that the at least one projection is designed as a survey, which extends in the longitudinal direction and in the circumferential direction of a connector part and / or extends the receptacle in the longitudinal direction and in the circumferential direction of the other connector part.

Preferably, it is provided that the projections and the receptacle are dimensioned at complementary connector parts so that in the receptacle of at least one projection is receivable and that is not the case with each other not complementary connector parts. So it is conceivable, for example, that with complementary connector parts, the projections can be completely inserted into the receptacle and this is not the case with non-complementary connector parts. As a result, in the case of non-complementary connector parts, a collapse of the connector parts is possible, if at all, to the extent that the opening element does not open the septum, as explained in greater detail above.

In a further embodiment of the invention it is provided that the opening element is designed as a preferably tapered neck, which forms a fluid-flow area in the connected state of the connector parts. This connecting piece is set back against contact with the open end region of the connector part on which the connection with the other connector part is made.

Furthermore, it can be provided that both connector parts have gripping surfaces which lie in the locked state of the connector parts in a common area and which are not in a non-locked state of the connector parts in a common area. Thus, an optical control is readily possible as to whether the two connector parts have been locked in the desired position or whether this is not the case. Also in this case is alternatively or additionally one Haptic control in reaching the desired position of the connector parts conceivable, which is also mitumfasst of the invention.

Further details and advantages of the invention will be explained in more detail with reference to an embodiment shown in the drawings. Show it:

- 10 -

FIG. 1 shows the main body 10, which forms the first connector part together with the additional part shown in FIG. 3 (in the following: coding ring).

The second connector part is formed by the hose connector 40 shown in FIG.

The main body shown in Figure 1 remains the same for all variants of the connector.

This has the advantage that there is a possible contact with a medical solution or a pharmaceutical with only one component.

Since the color coding is carried out via the other connector components, namely via the coding ring 30 and the tube connector 40, in the base body 10 according to FIG. 1, any entry by elutable or contact-active color granules can be dispensed with. In this way, interactions between any color granules and medical solutions are minimized, as there are no variations in material in direct contact with the drugs or solutions.

In Figure 1, the reference numeral 12 shows a break-off cone and the reference numeral 13 a hose seat (solution side) for attaching a hose. These two parts form the solution-contacting side.

The reference numeral 14 indicates a gripping surface of the main body or the first connector element, which is flattened and intuitively dictates the correct Konnektionsposition by their feel and appearance.

By the reference numeral 15, a preferably circumferential locking lug for the coding ring shown in Figure 3 is shown. Optionally, a welded connection is possible. The reference numeral 16 indicates the sealing surface for the sealing element exemplified in FIG.

The sealing element according to FIG. 2 with the reference numeral 20 can be, for example, a sealing disk made of silicone, which has a slotted opening 22. Optional sealing elements are an O-ring, a sealing washer or another elastic element.

In principle, a different design of the sealing element or by the introduction of a further sealing element and a double seal can be realized, but this is associated with increased effort and increased costs.

The reference numeral 30 in Figure 3 identifies the coding ring, which is attached to the left in Figure 1 shown portion of the body.

The coding ring fulfills the tasks of mechanical coding with the hose connector shown in Figure 4, a color coding and the pressing and holding the sealing element, preferably without welding or gluing.

An anti-rotation of the coding ring 30 is given by the geometry of the locking lugs 15 and the welding lugs and the openings 32 of the Codierrings. By appropriate shaping of the locking lugs on the base body of the coding ring is preferably unsolvable snapped onto the base body 10 or welded there or otherwise fixed.

In Fig. 3, reference numeral 31 shows coding pins, i. the projections according to the invention, the positions of which can vary from connector to connector.

As can be seen in FIG. 3, these coding pins extend firstly in the longitudinal direction of the coding ring 30 and secondly in the circumferential direction. The reference numeral 32 indicates the breakthrough for the latching lugs 15 of the base body 10 and at the same time serve as rotation of the encoder ring 30th

The reference numeral 33 denotes a pin for the bayonet closure, which cooperates with a groove of the hose connector 40 according to FIG. 4 and thus forms the closure element.

By the reference numeral 34 is a visible even in the connected state ring of the coding ring 30, which is used for color coding. Preferably, the entire coding ring 30 is colored.

The reference numeral 35 finally indicates a pressing surface, which is located on the inside and which serves for pressing the sealing element, which in turn bears against the sealing surface 16 of the base body 10 according to FIG. The sealing element is thus pressed between the base body and the coding ring.

The reference numeral 36 denotes a recess, which serves as Berührschutz the sealing element.

Due to the coloring and the mechanical coding, the connection is unique and unmistakable.

As stated above, FIG. 4 shows the hose connector which forms the counterpart to the main body 10 and to the coding ring 30.

Preferably, only the respectively correct hose connector fits on the correspondingly matching coding ring 30. The feedback of a successful and secure connection takes place both visually and acoustically and haptically.

As can be seen from FIG. 4, the coding ring has flattened gripping surfaces 41, which intuitively determine the correct connection position. In the connected state These gripping surfaces lie in a plane with the corresponding surfaces 14 of the base body 10.

The reference numeral 42 denotes the receptacle in the sense of the present invention, which is formed as an internal recess which extends in the circumferential direction.

This recess serves to receive the coding pins 31 of the coding ring 30. Their position can vary from connector to connector.

The reference numeral 43 denotes an opening for the pin 33 of the bayonet lock on the coding ring 30. As can be seen from Figure 4, the groove for receiving the pin 33 extends to one in the longitudinal direction of the hose connector and the other in the radial direction.

The reference numeral 44 locking elements are marked, which serve to secure the connection against self-loosening of the connection and for optical and haptic feedback. Thus, it is readily apparent to a user that a snap and thus a sufficient locking has occurred.

The color coding, which provides an unambiguous association between the hose connector and the main body or the coding ring 30, can take place, for example, via a completely colored hose connector 40, which may have the same color as the coding ring 30 or also via a keyed-up or colored ring. What is essential is a color assignment between the hose connector on the one hand and the first connector part, i. the main body or the coding ring 30 on the other.

Reference numeral 46 denotes a cone, ie the opening element in the sense of the present invention. This cone serves to seal the connection by means of an elastic sealing element according to FIG. 2 on the main body. By the reference numeral 47, a recess of the cone is provided as Berührschutz and the reference numeral 48 is a chamfer for easy fine positioning.

The reference numeral 50 in Figure 5 indicates a protective cap, which can be plugged onto the basic body 10 provided with the coding ring 30. As can be seen from Figure 5, this cap 50 has a circumferential Codieraussparung 51 so that the cap 50 can be placed on any coding ring 30 and thus universal. With this principle, the use of a universal adapter could be realized, which, for. has the ability to provide a standard luer connector on all connectors.

FIG. 5, right-hand side view, shows a sectional illustration and illustrates that, in position 52, the sealing disk according to FIG. 2 is supported in order to close the sealing disk when not in use and thus to keep it tight.

In Figure 6, the tubing connector, i. the second connector part according to the invention characterized. As can be seen from FIG. 6, a snap-on color coding ring 60 is provided, which may have a different color than the tube connector itself. If monochrome coding or coloration of the tube connector itself should not be sufficient, one or more such color coding rings 60 may be used Color palette can be expanded as desired. Of course, this applies not only to the side of the hose connector, but also to the side of the main body or of the coding ring.

This color coding in the form of the ring would also make it possible to completely dispense with colored plastics in the areas of the entire connector that come into contact with the solution.

FIG. 7 shows the principle of the connection of the two connector parts. According to Figure 7, left view, the latch or lock is open and closed in Figure 7, right view.

As can be seen from FIG. 7, right-hand illustration, in the locked or closed position, the grip region of the first connector part and the grip region of the second connector part are in one plane. The handle area of the connector is thus designed so that when touched ergonomically results in a preferred position in the fingers, i. a pre-positioning according to Figure 7, left view. By the rotational movement is then achieved in Figure 7, right representation.

By pre-positioning the Finding the locking elements is much easier.

As can be seen further from FIG. 7, both the first and the second connector part have a bulbous region whose radius to the connector axis is greater than the distance of the grip regions from the connector axis and which is round. Furthermore, both connector parts have one or more almost flat or planar areas, which forms the grip area and is set back relative to the outer circumference of the curved area. The ribbing in the grip areas provides support even with a wet connector. Chamfers on the caps facilitate fine positioning.

As can be seen from FIG. 7, right-hand illustration, in the locked position, the pin 33 of the coding ring 30 is accommodated in the end region of the groove of the hose connector 40 and is fixed there by the mentioned locking elements. In this way, an optical control of the complete locking is possible.

FIG. 8 illustrates in a sectional representation that at the point A in the connected and locked state, the cone 46 penetrates the sealing disk 20 and opens it, so that a flow through the connector is possible.

The connector is thus connected correctly. FIG. 9 shows a situation in which two non-complementary, ie "wrong", connection parts are to be connected to one another.

As can be seen in Figure 9a, in this case there is a gap at location B and, due to the fact that the pin 33 is not yet received in the circumferential direction of the groove, rotation is prevented.

As can be seen from FIG. 9b, the cone in this case does not penetrate the sealing disk (see reference C), so that no flow is possible.

The connection is prevented by having the coding pins, i. the projections are made wider than the recording on Codierring, so that insertion is not possible.

In contrast, Figure 10 shows an embodiment with complementary connector parts, in which the coding pins 31 fit into the recess 42, so that the gap B can be overcome and the two connector parts can be completely pushed together and then rotated.

Further preferred properties and advantages of the connector according to the invention are described in more detail below:

There is maximum mechanical security, i. with wrong connector parts no connection and no flow is possible because the cone or the opening element still stops in front of the sealing disc or the septum.

Safe handling is possible by a color coding and by the intuitive handling (basically known bayonet lock) with positioning aid by gripping surfaces. There is preferably no springback element which acts directly on the pin as in a known bayonet closure. A springback results from the septum, which should not be understood in this sense as a springback element.

With the Diskonnektion there is a drip protection and a flow barrier when using a sealing washer.

Due to the recessed sealing surfaces there is a contact protection.

The color coding can be variable and be formed for example by rings or other markings.

Long-term product contact can be carried out only a constant component, without having this color or material variations.

An accidental Diskonnektion is prevented because locking elements and sealing prevent a single turning back. Maximum security against disconnection in case of sudden tensile loads is guaranteed by the principle of bayonet closure. In contrast to a screwing movement, embracing is preferably not necessary when closing the connector. Sufficient is a twist by a few degrees.

This is also advantageous in view of the fact that the hose is correspondingly twisted only a little.

There is a defined end position of the lock, defined locking forces and locking position with respect to the sealing elements inside the connector.

The connection can not be too light or too tight. It should be designed in such a way that it is not self-releasing and also not too strong, so that it is basically insoluble. The feedback of a closed connector can be visually confirmed by the position of the grip surfaces and the visible bayonet closure. An acoustic and haptic feedback by locking the shutter is conceivable and advantageous.

People with poor eyesight can also operate the connector largely "blindly" because it is not absolutely necessary to use color coding for the correct connection, for example because of the orientation of the grip surfaces or the acoustic or haptic feedback of the complete Orientation of the catch.

Preferably, the basic body according to FIG. 1 and the universal protective cap according to FIG. 5 are the same for all connectors, thus a cost reduction is possible for very large quantities without sacrificing safety.

Preferably, solution-contacting is always the same component.

The principle of the universal protective cap according to FIG. 5 can also be converted to a universal adapter that fits all connectors.

The coding ring according to FIG. 3 and the sealing element according to FIG. 2 are preferably adhesively bonded and welded, but are fixed in their position only by means of non-detachable latches. However, welding and gluing remain an optional way of joining.

The number of possible permutations is theoretically unlimited by the free number and positionability of the Codierstifte and is limited only by the available space of the connector, which is ultimately determined by the size of the connector. By inserting a third coding pin, for example, higher-level solutions are also conceivable which fit on several but not all subgroups. Thus, for example, it is conceivable that a connector A and a connector B are incompatible with one another, that a "master key C" fits both the connector A and the connector B. The "master key D" can then in turn match all counterparts ,

The embodiment and a preferred embodiment of the invention relates to a bayonet-like closing unit without a spring element would be necessary as well as the coded by the mechanical coding of the connection.

The functionality of the connector is self-explanatory, intuitive and confusing, with a large number of feedback to the user as to whether the connection was closed correctly or not. Operating errors are largely excluded, even with untrained specialist personnel. The operability is also intuitive for laymen and the blind, even for patients who connect themselves, e.g. in home dialysis.

As noted above, the number of possible encodings is limited only by the size of the connector. It is possible to use a connector as a master key to implement several master keys with subgroups in this encoding style.

Initially, the field of application of dialysis was carried out. However, the present invention is not limited to this scope. Also, it is not necessarily intended to be limited to a medical indication. Wherever a connection of fluid- and / or gas-carrying line in the low-pressure area is required, which is to be confused and touch-proof, the connection according to the invention is conceivable. It does not matter whether the principle is applied with a connector once or with a connector that has been used several times. Depending on the embodiment, the advantages of the connector can be stated as follows:

Maximum mechanical interchangeability, d. H. with wrong connection partners, no connection and no flow is possible because the cone still stops in front of the sealing disc.

 - Color coding

 - Intuitive handling (the principle of the bayonet catch is familiar to everyone and obvious at first glance.) Positioning aid is given to the user through specified grip surfaces).

 - No constructive own spring element required (When using a gasket, but occurs a slight spring-back effect, which can be quite advantageous for the handling of the connector.)

 - Drip protection and flow barrier in case of disconnection (when using a sealing washer)

 - Protection against contact due to recessed sealing surfaces (compared to standard luer connectors)

 - Variable color coding (optional)

 - Long-term product contact only one component is present, which can always be configured the same for different connectors with different color and / or material variations.

 - No accidental Diskonnektion possible because locking lugs and sealing prevent a single turning back. Maximum safety against disconnection in the event of sudden tensile loads is ensured by the principle of bayonet locking.

 - In contrast to a screw movement, no embracing when closing the connector is necessary

 - The hose is only twisted by a few degrees.

 - Defined end position of the lock, defined locking forces and locking position with respect to the sealing elements inside the connector

- Optical feedback of a closed connector through the aligned position of the grip surfaces and through the visible bayonet lock. - Acoustic feedback, the lock audibly engages.

 - Haptic feedback, the lock noticeably locks.

 - People with poor eyesight can also operate the connector "blind." For correct connection, it is not absolutely necessary to recognize the color coding of the connector.

 - Body and universal protective cap or additional part are the same for all connectors, so that a cost reduction is possible for very large quantities, without compromising safety.

 - Construction of a universal protective cap or a universal adapter for all color and coding variations possible.

 - The coding ring and the sealing element can be fixed without sticking and welding, but only by non-detachable Verschnappelemente in their position (welding and gluing remains but an optional possibility of connection).
